Abstract

The invention provides a method and a device for reducing vibration noise of a motor. The method for reducing the vibration noise of the motor includes a, acquiring measured values of the frequency and the amplitude of the vibration noise of the motor and storing the measured values; b, computing theoretical values of the frequency and the amplitude of the vibration noise of the motor according to calibration parameters of the motor; c, comparing the measured values acquired in the step a to the theoretical values computed in the step b, and computing pre-compensation quantities for the frequency and the amplitude of the vibration noise of the motor; d, generating a novel control parameter according to the pre-compensation quantities; f, generating PWM (pulse width modulation) signals according to the novel control parameter; g, controlling the motor according to the PWM signals. The method and the device have the advantages that the measured values of the vibration noise of the motor are compared to the theoretical values of the vibration noise of the motor, pre-compensation can be carried out on the motor, motor control strategies can be adjusted, accordingly, the vibration noise of the motor can be reduced, the method is simple and reliable, the cost is low, and the service life of the motor can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of motor noise control, and in particular relates to a method and a device for reducing vibration noise of a motor. Background technique [0002] With the improvement of people's income, higher and higher requirements are put forward for the quality of life, and the noise and environmental pollution are becoming more and more unbearable. As part of urban development, various motors have been applied to all aspects of people's lives, followed by motor noise that has a great impact on everyone's lives. Especially in the aerospace field, electronic equipment is required to be light in weight, small in size, and high in reliability, and even integrate the motor and controller. Device-related components fail, resulting in difficult maintenance, increased maintenance costs, and reduced customer experience. Therefore, how to effectively reduce the vibration and noise of motors and improve the reliability of motor...
